UNITED STATES PATENT OFFICE MOTOR-SLED.

I Specification of Letters Patent.

Patented Nov. 13, 1914.

To all e'vhom it may concern Be 1t known that I, CUs'rER LEVI TrixoEAN, a citizen of the United States, residing at Bigfork, in the county of Itasca and State of Minnesota, have invented anew and use ful Motor-Sled; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The aim of this inventlon is to provide an improved motor propelled ,sled having means to hold the-motor againstoperation,

until the operator-is kneeling or otherwise on the sled, then the holding means may be released'by the foot of the operator, which in turn will release the motor,- which will impart motion to the sled.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

Inithe drawings :Figure'1'is a view in perspective showing a portion of the sled broken away illustrating the motor propelled mechanism and the holding means therefor. Fig. 2 is a longitudinal'sectional view. Fig. 3 is a transverse sectional view on line 3-3 of Fig. 2.

Referring more especiallyto the drawings, 1 designates the sled, which may be of any suitable construction or configuration.

Journaled in bearings 2 of the sides or runners 3 of the sled are shafts or axles 4 and 5, with which-the wheels 6 and 7 are rotatable. One end of the axle 4 is provided with a rectangular or square pintle 8 to receive a key 9, for rotating the axle 4, in order to wind the main spring 10, one end of which is connected at 11 to the axle, while the other end is connected to a pin l2of'one of the sides or runners of the .sled. Projecting radially from the axle 4 is a double blade arm 13, which is constructed with a sleeve 14 riveted or otherwise secured on theaxle 4. Projectmg downwardly -from;the under face of the top 15 of the sled is a spring arm blade16.

the angle end 17 being fixed to'the topas at 18. This spring arm blade normally hes in the path of the arm 13, to prevent the axle or shaft .4 from revolving by the action of the main spring 10. Secured tothe spring blade 16 as shown at 19 is a rod 20, the rear portion of which is supported in a U-shaped staple or strap 21, and terminating in an upwardly extending toe-piece 22. I

To allow the sled to be propelled forward, the operator kneels, or otherwise conveniently arranges himself on the sled, and in such wise as to permit the toe or the shoe to engage the toe or foot piece 22, then'by pushing the toepiece of the rod 20 rearwardly, thereby throwing the spring arm from the path of the blade arm of the axle or shaft 4:, the main spring will .be allowed to unwind, thereby imparting motion to the axle or shaft 4 and its wheels, which will cause the sled to move forwardly. 4

The invention having been-set forth, what is claimed as new and useful is 1.. A motor propelled sled comprising runners, axles'journaled in bearings of the runners and including wheels, one of the axles constitutingan operating shaft, a motor carried by the operating shaft, a sleeve fixed to the operating shaft and provided with-a reinforced double-blade'darm, means on the sled to engage said arm to hold the motor against operation, and adevicemanually actuated to actuatethe means to release said arm.

ners and including wheels, one 0f the axles constituting an operating shaft, a motor carried by -the operating shaft, a sleeve fixed to 2. A motor propelled sled comprising runners, axles ournaled 1n bearings of the run-- the operating shaft and provided with a re- 1 inforced double-bladed arm, a spring arm upon the bottom of the sled arranged in the path of the arm of the operating shaft, a
